What Are the Essential Procedures for a Piston Ring Set Service and Repair on Ford Crown Victoria?

When servicing the piston rings of the engine, operate according to cleaning and inspection instructions of the crankshaft, camshaft, cylinder head and valve train. The subassemblies (such as cylinder head and piston) will have to be disassembled and reassembled. Where there is no special service procedure available use the engine service documentation as a guide.

Is the Piston Ring Set Inspected for Ring Land Damage or Accelerated Wear, and is the Piston Ring-to-Groove Clearance Measured on Ford Excursion?

Examine the piston for any damage to the ring land or signs of excessive wear, and check the clearance between the piston ring and groove. If the clearance is not within specifications, replace components as needed.
